MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI

Advanced Functional Materials, EarlyView.
Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.

Peak-to-average power ratio reduction of FDRM

2005 International Symposium on Intelligent Signal Processing and Communication Systems, 2005
Frequency Domain Reciprocal Modulation (FDRM), originally developed by T. D. Williams [1, 2], is an enhanced method of modulation to complement Orthogonal Frequency Division Multiplexing (OFDM) techniques. FORM was proposed to solve the problem of very fast dynamic multipath distortion in wireless communication environments.

Peak-to-average power ratio versus instantaneous-to-average power ratio for OFDM

2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008
In the literature, peak-to-average power ratio (PAR) is often used as an indicator for the dynamic range of OFDM signals. PAR is an extreme value statistic and can present an overly pessimistic view of the signal. Instantaneous-to-average power ratio (IAR), on the other hand, reflects more accurately the characteristics of the sample population.

Peak-to-Average Power Ratio of OTFS Modulation

IEEE Communications Letters, 2019
In this letter, we analyze the peak-to-average power ratio (PAPR) of orthogonal time frequency space modulation (OTFS) waveform. Towards this, we consider modulation symbols on an $N\times M$ delay-Doppler grid, where $N$ and $M$ are the number of Doppler and delay bins, respectively.

On the distribution of the peak-to-average power ratio in OFDM signals

IEEE Transactions on Communications, 2001
Summary: The distribution of the peak-to-average power ratio (PAPR) in strictly band-limited orthogonal frequency-division multiplexing (OFDM) signals is studied. Assuming that the baseband OFDM signal is characterized as a band-limited complex Gaussian process, we first attempt to derive the exact distribution of the PAPR in the band-limited OFDM ...

DMT signals with low peak-to-average power ratio

Proceedings IEEE International Symposium on Computers and Communications (Cat. No.PR00250), 2003
This contribution proposes a new family of methods to reduce the peak-to-average power ratio (PAR) in discrete multi-tone (DMT) and orthogonal frequency division multiplexing (OFDM) systems. This method avoids the use of extra inverse fast Fourier transformations (IFFT) as were used in some previously published techniques, but instead is based on ...
